STOCK-SHED DOOR.

Application filed May s, 1923; semi-Nc. 637,51af

certain, new and useful Improvements in Stock-ShedfDoors, of which the following yto is a specification.

1 This invention relates'to new and useful improvements instock shed doors.

`An important object of the invention is provide a door for stock sheds or the like ythat may be actuated by the animals housed thereinfor the purpose of allowing vthe same to enter and leave at will.

A further object of the invention is tof provide an `improved yhingefor swinging stock shed doors wherein the doors may be displaced `vertically `or laterally from the limited arc of movement of an ordinary swinging door to allow for the hurriedv entrance of morethan one animal at a time 'during the driving of a drove of animals provide `,a flexible y into a shed. i. 25.

A further object of the invention is to hinge vfor swinging doors wherein a larger hingingzone is provided than heretofore used for such structures.

A further object of the invention is lto provide an improved locking means for a door equipped with the type of hinge rel ferred to above.L

`Other objects and advantages ofthe ini vention will be apparent during the course of the following description. n

In the accompanying drawing forming a part of this specification and in which like numerals are employed to designate like parts throughout the same, t

Figure 1 is a front elevational view of a door frame with the improved type of door and hinge embodying this invention associated therewith,

Figure 2 is a longitudinal sectional view taken on line II--II of Fig. 1,

Figure 3 is a fragmentary sectional viewV of the improved locking means employed in connection withr the swinging door and flexible hinge embodying this invention.

Figuret is a front elevational view of a modification of the flexible hinge and swinging door embodying this invention and minus the locking means shown in Figs. 1 to 3 inclusive,`and t Figure 5. is" a longitudinal sectional view taken on line V-'V of the v,modification shown in Fig, 4r and shows the swinging door in dotted lines displaced vertically vfrom the ordinary are of a swinging door.

In the drawing, wherein for the purpose of illustration is shown the preferred embodiment of this invention, the numeral G designates the vertical side frame members of a shed door opening having associated therewith the transverse top piece 7 as shown. Referring `particularly to Figs. 1 to 3, inclusive, the top piece 7 is provided with a longitudinally extending groove S that is adapted for receiving the upper transverse edge of a relatively large piece of flexible material 9 secured therein. Secured to the lower transverse edge of the flexible material `9 is a swinging door 10 that is provided at its upper end with a cutout portion l1 adapted for receiving the flexible hinge which. is secured therein by means of a clamping plate 12 which is retained in position by any suitable fastening means, such as rivets. Slidably' engaging the opposite faces of the transverse top piece 7 are resilient strap members 13 that are provided with longitudinally extending slots 14 adapted for being engaged by the clamping bolts 15 whereby the said strap members may be retained in any desired adjusted position. By examining Fig. 3, it will be 'seen that the strap members 13 may be moved downwardly to engage the top portion of the swinging door 10 for the purpose of preventing free movement of the latter, thereby retaining the said door in substantially a locked condition. The lower transverse edges of the door 10 are provided with metallic plate members 16 having scalloped depressions 17 formed in their outer faces for the purpose of reinforcing the lower edge of the door. Should the door 1() be employed for sheds housing hogs or the like, the scalloped depressions 17 will aid the animals in rooting the door open.

Referring particularly to Figsjl and 5, it will be seen that the transverse top strip 7 is adapted for having the` relatively large flexible hinge member 9a secured thereto by means of the clamping strip 7a, while the `lower edge of the flexible hinge member 9a is secured to the swinging door 10a by means of a clamping strip 12a. In Fig. 5 the door 10a is shown in dotted lines in vertical displaced position with respect to the usual arc covered by a swinging door.

It will be seen that with the exceedingly llO large hinging zone provided by the flexible hinge member 9 embodying this invention, that the swinging door l0 may be displaced vertically, as shown in dotted lines in F ig. 5, and may also be displaced lateral-ly when positioned outwardly or inwardly of' the vertical side frame members 6. rlhe door may be further twisted on substantially a longitudinal axis for the purpose of' allowing an animal to pass through the opening by forcing against one longitudinal edge of the door. It is believed that the other leatures of construction possessed by this invention will be clearly understood from the above detail description.

It is to be understood that the forms of this invention herewith shown and described are to be taken as preferred examples of the same, and that various changes in the shape7 size, and arrangement of parts may be resorted to wit-hout departing from the spirit of the invention or the scope of the subjoined claim.

Having thus described the invention` l claim:-

The combination with a door iframe including a lintel; of a rectangular flexible strip extending` substantially from side to side of said frame and having its upper edge portion secured to said lintel, said strip depending below said lintel, and a door secured to and depending from the lower edge portion of said strip, the top of' said door being spaced below the lintel, and resilient fingers carried by said lintel and mounted for vertical sliding movement thereon, said fingers being arranged in pairs with the fingers oi each pair opposite each other and having inwardly bent lower ends bearing on the flexible strip when raised and on the upper part of the door when depressed.

In testimony whereof l afx my signature.
